The probability that atleast one of the two events A and B occurs is 0.6. If A and B occur simultaneously with probability 0.3, evaluate `P(barA)+P(barB)`.

Explanation

To solve the problem, we need to use the properties of probability. We are given the following information:

1. The probability that at least one of the two events A and B occurs, denoted as \( P(A \cup B) \), is 0.6.
2. The probability that both events A and B occur simultaneously, denoted as \( P(A \cap B) \), is 0.3.

We need to evaluate \( P(\bar{A}) + P(\bar{B}) \), where \( \bar{A} \) and \( \bar{B} \) are the complements of events A and B, respectively.
